TTYs for the deaf

It's a pity that the deaf TTYs are 5-bit rather than ASCII. The reason for my question had to do with my campaign to get the few people I care about to switch from PeeCees to timesharing computing, i.e., instead of using a PeeCee, paying for Internet service, etc., get an account on my VAX and dial into it from a Teletype. One of the problems is of course that no one has Teletypes any more. I was wondering if the deaf ones could be used, as in the current horrible state of the world it seems like Teletypes are now only used by the disabled, rather than by 100% bodily abled people who are more intelligent than the masses and want to use timesharing UNIX (or VMS or RSX or TENEX or ...) instead of a pee sea. BTW, has there ever been a Teletype model that did 300 baud instead of 110? Perhaps Model 35 or 37? My Courier V.Everything modems are great, and they can go down to Bell 103 or V.21, but to my knowledge they do not have an asynchronous pass-thru mode between the RS-232 TxD/RxD lines and the Bell 103 FSK modulator/demodulator, it always has to go through the modem's internal buffers, which requires it to know the baud rate, and as a result it can only operate at 300 baud with Bell 103 / V.21, even though this modulation scheme is in fact asynchronous and baud rate-oblivious for the range 0-300 baud. The end result is that they can't answer 110 baud calls MS
